3M™ Heat-Activated Acrylic Plus Tape ST1200 is a 1.20 mm (0.047 inch) thick, black acrylic foam tape, constructed with two different adhesives, used to attach weatherstrip and/or gasket seals for automotive and industrial applications.
  • Provides high adhesion and holding strength to automotive paint surfaces.
  • Conformable acrylic core delivers excellent wet-out and stress handling characteristics to maintain seal integrity.
  • Features a black, high-strength core resulting in improved bond line quality.
  • Offers the ability to tape seal components prior to high temperature processing.
  • Heat-activated adhesive on the non-liner side forms an immediate, consistent and durable bond to most EPDM formulations and TPE materials.
  • Liner-side adhesive is a pressure sensitive adhesive characterized by high adhesion and holding strength to many surfaces, including automotive paints and metals.
  • Utilizes a soft acrylic foam core uniquely designed for excellent conformability of the seal to the substrate.
  • Since product performance will depend on actual conditions within a specific application, it is essential that the user evaluate the 3M product to determine whether it is fit for a particular material purpose and suitable for the user’s method of application.
